Temperature control has a dirty secret: the cheap thermostat holds a degree on a good day and swings five on a bad one. When the process cares — injection molds, seal bars, ovens, greenhouses — a dedicated controller costs real money, and a big PLC…

Pump stations have a way of failing at 2 AM, during the storm, with a full sump and nobody on site. Two pumps, one lead and one lag — the lead wears out from all the starts while the lag sits pristine untill the day…

You cannot download a program to a PLC through a wall. But the cable question confuses more first-time users than any other step, so here is the map: three ways to connect, one of them always available, all of them configured in the same dialog.

Modbus is the lingua franca of industrial panels — HMI screens, VFDs, energy meters and SCADA systems all speak it. An xLogic controller speaks it natively, as master or slave, over RS485 or Ethernet. This tutorial wires up both and proves the link with the…

These are the questions we actually answer in support tickets — not the brochure ones. If yours is missing, message us and it will appear here with the answer. Both editors are free downloads. xLogicSoft is the FBD (function block diagram) editor for SR and…

Ten minutes. That is how long it takes to write, download and run your first xLogic program — even if you have never touched FBD before. The tools are free, the wiring is three screws, and the whole workflow fits on a desk. This tutorial…

Choosing the wrong PLC costs more than the price difference between two models. It costs a control cabinet rebuild, a missed delivery date, or a machine that needs a second PLC bolted beside the first one. The good news? For compact automation, the decision can…

A small packaging machine looks simple: a film roll, a heater bar, a cutter, a counter. Then you open the cabinet and find forty relays, three timers and a rat's nest of wire that nobody dares touch. Sound familiar? This is the classic machine that…

Your laptop has no serial port. It has not had one for three generations. Yet half the field-programming guides on the internet still assume a COM port, a 9-pin cable, and a screenshot from 2010. The xLogic family solved this twice over: a USB programming…

Greenhouses run on a simple lie: that the weather will cooperate. The moment it does not — a sudden heat spike, a wind storm, a power cut at noon — the crop pays the price, and the grower pays the invoice. A compact PLC does…

A pump station that runs on a pair of float switches and hope will fail at 2 AM, during the storm, with a full sump and a drowned basement. That is not pessimism — it is the standard failure mode of unautomated pumping. The fix…

Here is the scene: a machine stops, the maintenance man finds a failed timing relay, and the spare is a week away becuase it is a discontinued model from 2006. The fix that takes fifteen minutes and ends that whole category of problem: a programmable…

Walk through any panel and count the extra components: a 24V power supply bought becuase somebody defaulted to DC without thinking. The xLogic family ships in both 110-240VAC and 12-24VDC versions — SR-12AC, PR-12AC, PR-14AC, PR-18AC, SR-22AC, PR-24AC, PR-26AC and the EXM-8AC on one side;…

Two families, one platform, and a decision that just got a lot more interesting. The SR series was always the economical entry point; the PR family was the expandable workhorse. Then the SR firmware update landed — V0.16 on the SR-12, V0.05 on the SR-12-B,…

Here is a question that ends more arguments than it starts: what time is it at your machine, and does it know about daylight saving? A real-time clock with summer/winter timer support is one of those features that sounds trivial and becomes indispensable on the…
